What causes the ASR light to come on?
The ASR light is on for an issue with the throttle pedal position sensor located on the gas pedal. You may be able to reset the parameters without replacing any parts.
What does ASR mean in VW?
ASR or ESP (electronic stabilization program), as it is now referred to, is the first part of traction control. ASR uses the anti-lock brake sensors to determine if one driving wheel is spinning faster than another due to a loss of traction, over useage of the throttle, too much power for the road conditions, etc.
What are the symptoms of a bad accelerator pedal?
Symptoms of a Bad or Failing Throttle/Accelerator Pedal Position Sensor. Common signs of a faulty pedal position sensor include inconsistent engine response, reduced fuel efficiency, and the Check Engine Light coming on. The days of having to constantly adjust the throttle cable due to a loose nut on the carburetor are long gone.
How does the accelerator pedal work in a car?
Today’s modern cars, trucks, and SUVs are all equipped with an electronic throttle control system that contains an accelerator pedal position (APP) sensor. This sensor’s primary job is to monitor the position of the throttle pedal and send an electronic signal to open the throttle body as you depress the gas pedal.
Why does my car not accelerate when I press the gas pedal?
This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly.
Is there an app for the accelerator pedal?
Today’s modern cars, trucks, and SUVs are all equipped with an electronic throttle control system that contains an accelerator pedal position (APP) sensor.
What does it mean when ASR light?
Hi, ASR stands for Acceleration Slip Regulation. It is basically your traction control system on your Mercedes that prevents wheel spin when accelerating.
What is the ASR light in mercedes benz?

Why do I get false activation on my ESC?
The next false-activation scenario involves the ESC system. The source of the problem can be more than one sensor and can even be traced to alignment angles. The customer may not notice an issue until there is a mechanical problem with the brakes. In these cases, you may notice that one wheel is covered in brake dust.
Why does my traction control light come on when I accelerate?
Below are the top 5 causes of a traction control light coming on when you are accelerating. Wheel speed sensors are connected to your traction control system and engine control unit. These sensors are responsible for detecting the speed in which your wheels are rotating. Each wheel has its own sensor.
